The mesa was in shadow, but the nearer plain lay in full sunshine, hot and yellow, and the west wind was full of mountain fragrance.
Phil gave little skips as he went along.

Already he seemed like a different boy.

All the droop and languor had gone, and given place to an exhilaration which half frightened Clover, who had constant trouble in keeping him from doing things which she knew to be imprudent.

Dr.Hope had warned her that invalids often harmed themselves by over-exertion under the first stimulus of the high air.
"Why, how queer!" she exclaimed, stopping suddenly before one of the pretty places just above Mrs.Marsh's boarding-house.
"What ?" "Don't you see?
That yard! When we came by here yesterday it was all green grass and rose-bushes, and girls were playing croquet; and now, look, it's a pond!" Sure enough! There were the rose-bushes still, and the croquet arches; but they were standing, so to speak, up to their knees in pools of water, which seemed several inches deep, and covered the whole place, with the exception of the flagged walks which ran from the gates to the front and side doors of the house.

Clover noticed now, for the first time, that these walks were several inches higher than the grass-beds on either side.
She wondered if they were made so on purpose, and resolved to notice if the next place had the same arrangement.
But as they reached the next place and the next, lo! the phenomenon was repeated and Dr.Hope's lawn too was in the same condition,--everything was overlaid with water.
